Spatial and Temporal Variability of Heavy Metals (Lead, Copper, and Zinc) in Stormwater, Moss, and Street Dust in Portland, OR

Creator:: Bauer, Sophia O. A.
Abstract:: Lead (Pb), copper (Cu), and zinc (Zn) are known to have detrimental effects on aquatic and terrestrial ecosystems, and to human health both in rural and urban areas. Heavy metal contamination enters stormwater by atmospheric deposition and by the collection of surface particles during overland flow. Stormwater runoff in urban...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

Geochemical Fingerprinting of Metals from Non-Ferrous Smelting Emissions within Lake Sediments

Creator:: Rutila, Elizabeth C.
Abstract:: The research presented in this thesis seeks to further our understanding of the geochemical signatures that can be used to trace and quantify non-ferrous smelting emission inputs into the environment. Strong evidence suggests that emissions from the non-ferrous smelter in Trail, BC are the primary source of metals deposited from...

Evaluating Spatial Patterns of Heavy Metal Levels and Pb Isotopic Compositions of Peat Soils along the Red Dog Mine Haul Road in Northwest Alaska

Creator:: Melby, Kali M.
Abstract:: This study evaluates ore transport and other mining activities on metal levels in the remote Arctic ecosystem of Cape Krusenstern National Monument (CAKR) in northwestern Alaska. This monument is 50 km SW of Red Dog Mine, one of the world’s largest Pb–Zn mines. The Delong Mountain Transportation System (DMTS) haul...

Vitamin E effects on sterility of White Leghorn males following prolonged vitamin E deficiency

Creator:: Friedrichsen, Janet Valerie
Abstract:: One group of four adult White Leghorn male chickens was fed a diet containing 7.3% linoleic acid and 32.4 mg/ kg of added vitamin E (group IV) for 50 weeks which was designated as the positive control. A second lot (group I) containing 14 males received the same level of...

Vitamin E and the alpha-tocopherol transfer protein during zebrafish embryogenesis

Creator:: Miller, Galen W.
Abstract:: Vitamin E was first described in 1922 as an unknown factor required for impregnated rats to carry their offspring to term. In fact, when vitamin E was chemically characterized it was given the name "tocopherol" derived from the Greek: tokos = childbirth; phero = to bear; and –ol, indicating an...

Decadal Changes in Lichen and Vegetation Communities in Relation to Metal Deposition and Climate in Northern Alaska

Creator:: Di Meglio, Elisa B.
Abstract:: The Red Dog Mine transports concentrated zinc and lead ore in northwestern Alaska through Cape Krusenstern National monument along a haul road. High metal levels in the moss Hylocomium splendens along the haul road have been attributed to ore dust released during transport. The mine has implemented several pollution abatement...

Reciprocal Moss Ornament Transplant for Heavy Metal Deposition Rate and Spatial Variability

Creator:: Field, Gillette M. and Shiel, Alyssa E.
Abstract:: Air pollution and pollution patterns have become a hot topic over the last several years. Many studies have been launched due to the increasing concern with air quality. As urban areas grow, atmospheric heavy metal pollution grows proportionally. Reducing atmospheric heavy metal pollution, and consequent health issues, requires monitoring and...
